Paper surfaces – Characterisation and properties

F-course

This course gives you indepth knowledge about the paper surface science

Content

  • Surface chemistry of paper Surface chemistry of paper
  • Surface topography
  • Pore structure
  • Surface characterization techniques
  • Light scattering and paper gloss – Effect of surface properties
  • Wettability, capillarity, spreading, special focus on short term wetting
  • Mechanical properties (incl. fracture mechanics) of coating layers
  • Ink–substrate interaction

Learning objectives

After the course, the participants should be able to 

  • apply a wide range of techniques used to characterize paper surface structure, paper surface chemistry and print quality, and account for the validity of the results of the same characterisation techniques
  • explain interfacial phenomena like wetting, absorption, friction and adhesion
  • describe the relation between surface topography and paper optical properties, and
  • describe how paper surface properties affect ink-paper interaction and print quality in different printing technologies.
  • describe the surface cracking phenomena on the basis of converting processes, substrate properties and coating layer composition.

Pre-requisites

Basic knowledge in paper technology. Some knowledge in surface science is desired but not requested.
